Harvard, Oxford University, NYPL) – these are

in-print and in-copyright. A “preview” can be
substantial
Google Books
• “Full previews” may be given to books that are
in-copyright but out-of-print. The full book in
its entirety may be viewed online
• For books that are out-of-copyright, books may be
viewed, downloaded (PDF) and printed in their
entirety. Out-of-copyright books will be more than
70 years old so Google Books is a good source
for 19th and early 20th century books and
other material
